I Y Cofi'eelnfusers, of which the following is andV this central portion fis-"of an "area Be aimown maar, im@ .D Riom;

MER acitizen of the United States, residing at ew York city, in the county of New York vaml Stateof 'NewV York, have invented certain newv and .useful Improvements in a specification.

Mynvention a simple and compact device for use in connection with acoi'ee cup to prepare a cup Y; of coffee. of superior quality and without l 13 to enable t V theuseof other devices.' f,

It .isV also -theobject of vmy invention to.

provide an infusxng.V device for individual use socthatanyone ,may always prepare a cup of coeeof .uniformtquality and of a standardl strength suitable tothe individual tasteanddesire.-

'I have'illustrated a simple and convenient embodiment of the invention in the accomf' panying drawings inwhichf- Eig. 1 illustrates theinfuserpartly in sectionarranged in placel uponV a coffeeV cup shown inbreken -l1nes; Fig. 2 is a sectional view of a p ortiown` of the coverg'lan'd. 1 p A Fig. -3 shows .the cover in -`section andy ar.- ranged. to` supportthe receptacle -and lto catchthedrip therefrom afterA thecup of coee has been made.

1 Referring to the drawings 4 is a compara.

tively shallow receptacle which -is shaped and proportioned to fit easily upon the top of-a coil'ee Icup 5. .The lower portion 6 of the receptacle vis preferably reduced in size to fit in thecoil'ee cup and it is provided with a perforated bottom 7 over which a filter paper 8 is placed to support the co'ee 9 and prevent it from passing through the perforations in the bottom 7. A perforated plate 10 having a handle 11 is adapted'to be arranged upon the co'ee 9 and this plate not only acts as a water spreader to distribute the water throughout the charge of coil'ee, but it also serves to hold the coffee with suiicient compactness to prevent the particles thereof from Heating and moving about while the water is percolating through the coffee to and through the filter paper. The receptacle has one or more indentations '12 to hold the plate upon the charge of coffee' and the plate has one or more notches e insertion and removal of the' plate.

The cover has a flat centrally has'` for itsobjiect to provide d 4section 14"` of eirtondedfarem afdepressed stampedfroin a single'metal sheet. The flat' central portion 14 is vprovided as a support ing surface to rest upon a table top when the cover 1s arranged in position'for supi portmgthe receptacle as shown in4 Fig.' 3

slightly less than ythat ofthe bottom so that the receptacle may rest upon an annular shoulder 17 surrounding the flat central por tion 14. The annular shoulder 17 connects the 'central flat portion 14 with the depressed ring 15. yIt will b'e noted that" the receptacle is held with its perforated bottom7 spaced away from the'at portionv 14. In this position any drippings from the receptacle will be retained -upon the portion 14 within the annular shoulderf17.' The dei pressed. ring'l its snugly within the open top of thereceptacle'll and the beaded ring A16 lits snugly upon the open beaded edge 18 of thev receptacle whereby the cover is snugly fltted uponthereceptacle .in co'e'e infusing position shownin Fig.'1 to confine' 'the contents of the receptacle and prevent the escape of the steam or aroma therefrom.

I prefer to make. all the parts ofy thede'- vice from sheetaluminum by stamping or otherwise and this enables me to easily construct the parts 'so that the cover may be fitted very snugly upon the receptacle.- -To facilitate the removal of the cover from the receptacle I provide the cover withl a handle 19 which is preferably bent over the' beaded edge 16 and fastened by rivets 20 tothe cover at the bottom of the depressed ring 15. This handle is preferably bent downward from the flat central portion 14 so that in inverted position of the cover as shown 'n 4 this andle will project upward so hat 1t can be easily grasped. The receptacle is also proy vided with a suitable handle 21 and I have found that the cover may. be readily vremoved from the receptacle, even when 1t by the cup of uniform quality and of standard strength. A sutlicient charge of ground coffee is'placed upon the filter paper inthe bottom Vof the receptacle, then the' spreader plate is arranged in place in the receptacle and then the receptacle is placed upon a coffee c'up and filled with boiiing water after which the cover is arranged in place and the infusing allowed to proceed. i The resulting coffee is clear, rich and of a strength determined by the quantity of lground vcoffee em-- pllyed; if the 'same proportions of ground co ee and water are always used, and the coffee is of the same quality, the resulting Acup of coffee ywill always be of uniform strength and quality. The infuser isa convenient device fortravelers, and its compact .size and shape enables it to be conveniently carried in a small bag or packed in a trunk.

I have shown and described my invention in what I now conceive to be its preferred form but I reserve the right to make all changes in the construction and arrangement and proportion-of parts as may come within the scope of the accompanying claims.

I claim: l.. A codec infusing'device comprising a receptacle open at the top and having a perforated bottom, and a cover adapted to engage said top for closing the receptacle,said

cover having a substantially flat central portion of extended area, a depressed ring between the central portion and the edge of the cover, and an annular shoulder between the depressed portion and the central portion, said annular shoulderforming a support for the receptacle when the cover is arranged in inverted position and spacing the bottom of the receptacle from the central portion of the cover. v

2. A coffee infusing device comprising a receptacle openV at the top, a handle for the receptacle, a cover having a substantially cylindrical surface adapted to 'frictionally engage a. like inner surface of the receptacle and a'handle `fastened to seal the receptacle,

portion of to, the cover and adapted to be employed to gether with the first handle l'to seal.

' 3.. A coiiee infusing device comprising a receptacle having ahandle and open at the ",ton. a cover adapted to engage said open top for closing the receptacle and having a de- Pressed fing to fit within the receptacle and a beaded edge to engage the edgeof the receptacle, and a handle fastened to the cover l S" over. the beaded edge .outwardly lfrom the in the depressed ring thereof and projecting COVCI.

4. A' coffee mfusing ground coffee and a quantity of water, said receptacle being open at the top 'and having a. perforated bottom, a perforated plate artween the depressed portion and the central portion, said annularshoulder forming a support for the recentaoie when the cover is arranged in inverted position and spacing the bottom of the receptacle from the c en- 'tral portion of the cover.4

5. A coffee intusing device comprising ja yreceptacle open at the top and having a perforated bottom and a cover adapted to'enl.

gage said open top for closing the receptacle, said cover having a substantially fiat central break the device comi-arising a j receptacle adapted to receive a C arge .0f 6d portion of extended area and an annular shoulder surrounding said flat central portion, said annular shoulder forming a support for the receptacle when the cover isl arranged in inverted position and spacing-the Y bottom of the receptacle from thev central the cover.
